Co2 capture device

Abstract

A CO 2 capture device according to the present disclosure includes: a channel through which gas is passed; a first CO 2 adsorption member and a heat absorption member that are disposed in the channel; a first insertion port through which a fluid is inserted into the channel in such a manner that the fluid flows through the heat absorption member via the first CO 2 adsorption member; and a second insertion port through which the fluid is inserted into the channel in such a manner that the fluid flows through the first CO 2 adsorption member via the heat absorption member. The fluid is passed through the heat absorption member via the heated first CO 2 adsorption member to heat the heat absorption member. When heating the first CO 2 adsorption member, the fluid is passed through the first CO 2 adsorption member via the heat absorption member to heat the first CO 2 adsorption member.

What is claimed is: 
     
         1 . A CO 2  capture device that captures CO 2  from gas, the CO 2  capture device comprising:
 a channel through which the gas is passed to capture CO 2 ;   a first CO 2  adsorption member disposed in the channel;   a heat absorption member disposed next to the first CO 2  adsorption member in the channel;   a first insertion port that is provided in the channel and through which a fluid is inserted into the channel in such a manner that the fluid flows through the heat absorption member via the first CO 2  adsorption member; and   a second insertion port that is provided in the channel and through which the fluid is inserted into the channel in such a manner that the fluid flows through the first CO 2  adsorption member via the heat absorption member, wherein the fluid is passed through the heat absorption member via the first CO 2  adsorption member heated to desorb CO 2  to heat the heat absorption member, and when heating the first CO 2  adsorption member, the fluid is passed through the first CO 2  adsorption member via the heat absorption member to heat the first CO 2  adsorption member.   
     
     
         2 . The CO 2  capture device according to  claim 1 , wherein, when desorbing CO 2  from the first CO 2  adsorption member, the fluid is passed through the heat absorption member via the first CO 2  adsorption member, and CO 2  is discharged from a discharge port provided on a heat absorption member side with respect to the first CO 2  adsorption member in the channel. 
     
     
         3 . The CO 2  capture device according to  claim 1 , wherein the heat absorption member is a second CO 2  adsorption member,
 when heating the second CO 2  adsorption member, the fluid is passed through the second CO 2  adsorption member via the first CO 2  adsorption member to heat the second CO 2  adsorption member, and   when heating the first CO 2  adsorption member, the fluid is passed through the first CO 2  adsorption member via the second CO 2  adsorption member to heat the first CO 2  adsorption member.   
     
     
         4 . The CO 2  capture device according to  claim 1 , wherein the first CO 2  adsorption member and the heat absorption member have a honeycomb structure. 
     
     
         5 . The CO 2  capture device according to  claim 1 , wherein the fluid is H 2 O that is in a gas phase when the channel is in a reduced pressure environment.
